why does my Porsche 911 992 (2019-Present) air conditioning blow hot air

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the vehicle's battery to ensure safety while working on electrical components.
• Ensure the vehicle is parked on a flat surface.

2. Recover Refrigerant

• Using a refrigerant recovery machine, recover any refrigerant from the A/C system per EPA guidelines.
• Dispose of the recovered refrigerant according to local regulations.

3. Replace A/C Components

If low refrigerant is found:

• Refrigerant Refill:
  1. Reconnect the refrigerant recovery machine and add the correct type and amount of refrigerant (check specifications in the service manual).
  2. Monitor the pressure on the gauges to ensure proper fill.

If A/C compressor is faulty:

• Compressor Replacement:
  1. Remove the serpentine belt using a socket set.
  2. Disconnect electrical connectors from the A/C compressor.
  3. Remove the mounting bolts and take out the compressor.
  4. Install the new A/C compressor, ensuring all bolts are torqued to manufacturer specifications.
  5. Reconnect the electrical connectors and replace the serpentine belt.

If cabin air filter is clogged:

• Filter Replacement:
  1. Access the cabin air filter housing (typically located behind the glove box).
  2. Remove the old cabin air filter and clean the housing.
  3. Install a new cabin air filter, ensuring correct orientation.

4. Recharge the A/C System

• After replacing components, connect the refrigerant lines and recharge the system with refrigerant.
• Add oil to the A/C system if necessary, following manufacturer specifications.

5. Final Checks

• Reconnect the battery.
• Start the vehicle and run the A/C system. Check for proper operation and listen for unusual noises.
